Abstract

<P>PROBLEM TO BE SOLVED: To provide a door stay which allows the size of an arm projecting in the storage space of an enclosure to be reduced as much as possible so as to enhance the degree of freedom for the arrangement of devices to be stored. <P>SOLUTION: A door stay 1 includes a first arm 2 and a second arm 3 with respective one ends pivotally fitted to each other. The arms 2 and 3 are arranged to allow for relative rotation in a vertical plane to each other. The other end of the arm 2 is connected to a bearing member 5 which is rotatably supported in a horizontal direction at the lower part of the enclosure 22 so as to be relatively rotatable with a horizontal pivot pin 6. The other end of the arm 3 is connected to a bearing member 9 which is rotatably supported in a horizontal direction at the lower part on the inner side of a door 23 so as to be relatively rotatable with a pivot pin 10. The arms 2 and 3 are thereby bent upward with respect to each other, when the door 23 is rotated to close. The arms 2 and 3 are rotated in a horizontal direction relative to the enclosure 22 and the door 23, respectively, so as to increase the angle therebetween, when the door 23 is rotated to open. The arms 2 and 3 extend along an approximately horizontal straight line, when the door is opened. <P>COPYRIGHT: (C)2013,JPO&amp;INPIT

Description

  The present invention relates to a stay for holding a door that opens and closes an opening of a housing in an open position, and a cabinet equipped with the stay.

  In general, this type of stay has a pair of first and second arms whose one ends are rotatably connected to each other, and the other end of the first arm is connected to the housing and the other arm. The end portions are connected to the doors so as to be relatively rotatable in a horizontal plane (see, for example, Patent Document 1). The first and second arms have a substantially “<” shape as a whole, and the angle between the first and second arms increases when the door is opened and rotated. When the door reaches the open position, the angle between the doors becomes a large angle close to 180 °, and the first and second arms are arranged substantially in a straight line. This state is maintained by some means to prevent the door from rotating.

JP 2001-115720 A

In the above conventional door stay, there is a problem that the arm protrudes relatively large in the housing space of the housing, particularly when the door is closed, and the housing space is reduced or the arrangement of the storage devices is limited.
Therefore, the invention according to this application provides a door stay that can reduce the dimension of the arm projecting into the housing space of the housing as much as possible when the door is closed, and can increase the degree of freedom in arranging storage devices. It is intended to provide.

Hereinafter, the present invention will be described with reference to the accompanying drawings, but the present invention is not limited thereto.
The door stay 1 according to the present invention for solving the above-described problem is a stay for holding the door 23 that opens and closes the opening 22a of the housing 22 in the open position, and one end of each of the stays is relative to each other. A first and second pair of arms 2 and 3 pivotally attached to each other are provided. The first and second arms 2 and 3 are arranged to rotate relative to each other in a vertical plane. The other end of the first arm 2 is connected to a first bearing member 5 supported at the lower portion of the housing 22 so as to be horizontally rotatable by a pivot pin 6 in the horizontal direction. The other end of the second arm 3 is connected to a second bearing member 9 supported by the inner lower portion of the door 23 so as to be horizontally rotatable by a pivot pin 10 in the horizontal direction. Thus, the first and second pair of arms 2 and 3 are refracted upward when the door 23 is closed and rotated horizontally with respect to the housing 22 and the door 23 when the door 23 is opened and rotated. However, the mutual angles are increased, and when opened, they are configured to extend on a substantially horizontal straight line.
When the housing 22 has a fixed frame 24 surrounding the opening 22a, the stay 1 can have the following configuration. That is, the first mounting seat 7 is fixed on the horizontal lower frame 24 a constituting the fixed frame body 24, and the first bearing member 5 is horizontally mounted on the first mounting seat 7 by the vertical pivot pin 8. It is supported rotatably. The support member 13 is fixed to the inner side surface of the door 23, the second mounting seat 11 is fixed on the horizontal mounting surface 13 a of the support member 13, and the second bearing member 9 is mounted on the mounting seat top 11. It is supported by a vertical pivot pin 12 so as to be horizontally rotatable.
The stay 1 can take the following configuration. That is, one of the first arm 2 and the second arm 3 extends to the other end side beyond the pivot point 6 with the other arm, and at least a part of the upper edge of the extension portion. And an abutting portion that abuts against the upper edge of the other arm during extension and maintains the extended state.
Moreover, the cabinet 21 of the invention according to this application is configured such that the stay 1 having the above-described configuration is interposed between a housing 22 and a door 23 that opens and closes an opening 22a of the housing 22.

In the door stay 1 according to the present application, the arms 2 and 3 are refracted in the vertical direction. Therefore, when the door 23 is closed, the arms 2 and 3 protrude into the housing space of the housing 22 as much as possible. The degree of freedom of arrangement of the storage device can be increased.
Moreover, since the cabinet 21 of the invention according to this application uses the door stay 1 that is refracted in the vertical direction, the cabinet 21 can be used effectively without deteriorating the storage space of the housing 22.

It is a perspective view of a part of a cabinet equipped with a door stay according to an embodiment of the present invention, in which (A) shows a closed state, (B) shows a 45 ° open state, and (C) shows a fully open state. It is a front view of the state which opened the door in the cabinet of FIG. It is a front view of the stay for doors of FIG. It is a top view of the stay for doors of FIG. It is VV sectional drawing in FIG.

Embodiments of the present invention will be described with reference to the drawings.
In FIG. 1, the cabinet 21 includes a housing 22 and a door 23 that opens and closes an opening 22 a of the housing 22, and the stay 1 is interposed between the housing 22 and the door 23. The stay 1 is for holding the door 23 of the housing 22 in the open position. The casing 22 is provided with a fixed frame body 24 surrounding the opening 22a.

  The stay 1 includes a pair of first and second arms 2 and 3 that are pivotally attached to each other by a pivot pin 4 so as to be rotatable relative to each other. When mounted on the cabinet 21, the arms 2 and 3 are arranged with the pivot pin 4 facing horizontally so as to rotate relative to each other within a vertical plane.

  The other end of the arm 2 is coupled to the first bearing member 5 supported at the lower part of the housing 22 so as to be horizontally rotatable by a pivot pin 6 in the horizontal direction. The bearing member 5 is supported by a vertical pivot pin 8 (FIGS. 3 and 4) on a mounting seat 7 fixed on a horizontal lower frame 14a constituting the fixed frame body 24 so as to be horizontally rotatable.

The other end of the second arm 3 is connected to a second bearing member 9 supported at the inner lower portion of the door 23 so as to be horizontally rotatable by a pivot pin 10 in the horizontal direction so as to be relatively rotatable. That is, the support member 13 is fixed to the inner surface of the door 23, the second mounting seat 11 is fixed on the horizontal mounting piece 13 a of the support member 13, and the second mounting seat 11 is fixed on the mounting seat 11. The bearing member 9 is supported by a vertical pivot pin 12 (FIGS. 3 and 4) so as to be horizontally rotatable.
The first and second pair of arms 2 and 3 are refracted upwards when the door 23 is closed and closed (FIGS. 1A and 1B), and with respect to the housing 22 and the door 23 when the door 23 is opened and rotated. While being rotated horizontally, the mutual angle is increased, and when fully opened, it is configured to extend on a substantially horizontal straight line (FIG. 1C).

  In the illustrated embodiment, as shown in FIG. 5, the second arm 3 is formed by bending a plate material, and includes a pair of parallel side plate portions 3 a and a top plate portion 3 b that connects between the upper edges of the side plate portions. . The second arm 3 extends beyond the pivot point with the first arm 2 to the first arm 2 side. One end of the first arm 2 is inserted between the side plates 3a of the extended portion of the second arm 3 (FIG. 5), so that the top plate 3b contacts the upper edge of the first arm 2 when extended. Contact and maintain the stretched state. In this extended state, the angle between the first arm 2 and the second arm 3 is set to be slightly larger than 180 ° which is a dead point, whereby the door 23 moves in the closing direction. Is securely locked. Although not shown, the shapes of the first arm 2 and the second arm 3 can be interchanged.

  Now, when the door 23 is opened from the closed state of the door 23 shown in FIG. 1A, the arm 2 and the arm 3 are moved together with the bearing members 5 and 9 as shown in FIG. While rotating horizontally with respect to the housing 22 or the door 23, the mutual angle is widened. Then, in the fully open state of the door 23 shown in FIG. 1C, the door 23 is locked in a state where the angles of the arms 2 and 3 are slightly over 180 ° as shown in FIG. In order to close the door 23 from this state, it is only necessary to push the door 23 around while slightly raising the pivoting portions of the arms 2 and 3 so as to exceed the dead point and bending between the two.
